Greetings,
Your hacking guide is more than interesting, but I have some questions about the mentioned tools.
1.) | maman wrote: | | Modbin. I'm using the version 4.50.80C |
Modbin 4.50.80c is not the latest.
Please look at this page
2.) | maman wrote: | | Cbrom. I'm using the version 2.80. |
Does CBROM 2.80 really exists? If yes, where does it exist?
I am sure you mean 2.08.
Well CBROM 215 is really new, but look this page too and you will find CBROM217a.

yup you are right, I've mistyped the CBROM version, it should be 2.08  . I'll fix it. As for the modbin version, I think that's the latest for the Award version 4.51 PGNM, after that Modbin only works for award version 6.oPG or newer award bios.

4.50.82 is the latest modbin2 for award 4.5x bioses.
ModBin6 1.00.48 is the latest for 6.00 bioses. There's a ModBin6 Beta 2.0 as well which sometimes works better on newer releases but it still has some major flaws (crashing and all that).

Ah, and it wouldn't hurt to tell people you are replacing your EPA logo with this routine. At least, that is what it looks to be to my untrained brain.

No, not the EPA logo, but the routine to display it. The EPA logo itself is in a different file such as the epa file displayed when you are seeing your bios component using cbrom. Btw, I've updated the article slightly, due to some more "new" discoveries I made in this last few days  .

OK, could you please explain what you can do with this routine? I have seen some modifications in bioses, but I'm failing to see what you can achieve with this one.

My routine (that replaces the "EPA procedure") actually patch my chipset's memory controller in the Hostbridge (VIA 693A). It sets the IOQ (In Order Que Depth) to 4 level , sets the DRAM bank interleaving to 4-way, activates the fast TLB (Translation Lookaside Buffer) lookup, and activates "allow pages of different banks to be active" in the DRAM controller. That's all about it. Actually we can "inject" more code in the "EPA procedure" area, and if that's not enough, just make call to our "additional procedure" in the "empty" area (which contais padding bytes) in the last 4 kbytes of the first 64 kbytes (E000h segment).

moderator, if you don't mind, please add link to my bios hacking tutorial in the collected wisdom. I just think there might be some people who might need it. I didn't meant to be "famous" here, I just want to help others . It is if you don't mind at all. Thx
